5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.), with 16-byte FIFOs

6.2 Internal registers

The SC16C2550B provides two sets of internal registers (A and B) consisting of

12 registers each for monitoring and controlling the functions of each channel of the

UART. These registers are shown in Table 5. The UART registers function as data holding

registers (THR/RHR), interrupt status and control registers (IER/ISR), a FIFO Control

Register (FCR), line status and control registers (LCR/LSR), modem status and control

registers (MCR/MSR), programmable data rate (clock) control registers (DLL/DLM) and a

user-accessible Scratchpad Register (SPR).

[1]

These registers are accessible only when LCR[7] is a logic 0.

[2]

These registers are accessible only when LCR[7] is a logic 1.
